Freescale AO48 00/ MC48 00 Dual N-Channel 30-V (D-S) MOSFET These miniature surface mount MOSFETs utilize a high cell density trench process to provide low rDS(on) and to ensure minimal power loss and heat dissipation. Typical applications are DC-DC converters and power management in portable and battery-powered products such as computers, printers, PCMCIA cards, cellular and cordless telephones. • • • • PRODUCT SUMMARY VDS (V) rDS(on) m(Ω) 58 @ VGS = 4.5V 30 82 @ VGS = 2.5V Low rDS(on) provides higher efficiency and extends battery life Low thermal impedance copper leadframe SOIC-8 saves board space Fast switching speed High performance trench technology ID (A) 5.0 4.2 1 8 2 7 3 6 4 5 o ABSOLUTE MAXIMUM RATINGS (TA = 25 C UNLESS OTHERWISE NOTED) Parameter Symbol Limit Units Drain-Source Voltage 30 VDS V Gate-Source Voltage VGS ± 12 o TA=25 C a Continuous Drain Current o TA=70 C b Pulsed Drain Current a Continuous Source Current (Diode Conduction) ID TA=25 C a o TA=70 C Operating Junction and Storage Temperature Range THERMAL RESISTANCE RATINGS Parameter Maximum Junction-to-Ambienta ± 30 IS 1.7 PD Steady State 2.1 1.3 TJ, Tstg -55 to 150 Symbol t <= 10 sec 4.1 IDM o Power Dissipation 5.0 RθJA Maximum 62.5 80 A A W o C Units o C/W C/W o Notes a.
